I need help (in a very simple way) due to calculate the torque needed to let a sphere coming out of a countersink.
I'll try to explain better my application with the components involved:
1. a spring that apply a Force F=76.26N (nominal length 14mm) at 11.6mm of compression: these values could be variable;
2. a ball bearing sphere 6.0mm diameter: this is a fixed value;
3. a countersink of 0.5mm x 45° in a 5.0mm hole (the height and the angle could be variable);
The spring push the sphere inside the countersink hole.
The countersink holes are cnc in a coffee milling appliance and I need to know the torque in Nm to let the sphere coming out of the countersink (this is used to avoid problems on the driving motor).
If needed I can try explain better with a drawing.
